Abstract
The utility model discloses a kind of turbine shroud Milling Process fixing device, first strut is set on pedestal, the epimere of first strut is threaded, and the both sides up and down of the first platform are locked in the top of the first strut by upper locking nut and lower locking nut, and the first strut passes through the through-hole of turbine shroud；Through position is also set up on pedestal, through position is connect by shaft with the lower end of the second platform, and the upper end of the second platform is resisted against the side of the first platform；The abutting of second platform and turbine shroud, after the second strut passes through the second platform and turbine shroud, one end of the second strut wears the second compact type face and lock nut, and the other end of the second strut is rotary with lower end lock nut；The utility model has the advantages that：As a result of the positioning of locking nut form, therefore, position of the platform on strut is adjustable, has adapted to the turbine shroud of different size；And the pivot structure of the second platform, it has been also adapted to the rotation angle of different housings.
Description
Technical field
The utility model is related to machinery field, specifically a kind of fixture of turbine shroud Milling Process.
Background technology
The outer surface of turbine shroud is an irregular curve form, and is also provided with one in its outer surface convenient for peace
The type face of dress, such as the 16 of Fig. 1, which is generally processed by the way of milling, but since the surface shape of turbine shroud limits,
It is less susceptible to position；In addition, the turbine shroud shape of same model is similar, but size is different, and the prior art is for every
The turbine shroud of kind model is respectively provided with a sleeve clamp, increases cost.
Invention content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of accurate positioning, and adjustable folder
Processing of the tool for turbine shroud, specific technical solution are as follows：
The first strut, the first strut is arranged on the pedestal in a kind of turbine shroud Milling Process fixing device, including pedestal
Epimere be threaded, the both sides up and down of the first platform are locked in the upper of the first strut by upper locking nut and lower locking nut
It is square, the first support type face is arranged above upper locking nut, the first strut passes through the through-hole of turbine shroud；It also sets up and turns on pedestal
Platform is connect, through position is connect by shaft with the lower end of the second platform, and the upper end of the second platform is resisted against the side of the first platform；The
The abutting of two platforms and turbine shroud, after the second strut passes through the second platform and turbine shroud, one end of the second strut wears the
The other end of two compact type faces and lock nut, the second strut is rotary with lower end lock nut；It is also set between first platform and pedestal
Positioning branch cylinder is set, the positioning branch jacket casing is located at the outside of the first strut.
To prevent the abrasion of two platforms, the face of the first platform and the second contact with platform is cambered surface.
The diameter of first strut and the second strut needs the internal diameter with the through-hole on turbine shroud to match.
The utility model has the advantages that：As a result of the positioning of locking nut form, therefore, position of the platform on strut
It sets adjustable, has adapted to the turbine shroud of different size；And the pivot structure of the second platform, it has been also adapted to the rotation angle of different housings
Degree.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is illustrated below in conjunction with the accompanying drawings, as shown, the utility model includes pedestal 1, the pedestal
The first strut 2 of upper setting, the epimere of the first strut 2 are threaded, the both sides up and down of the first platform 3 by upper locking nut 5 and under
Locking nut 4 is locked in the top of the first strut 2, and the top of upper locking nut 5 is arranged the first support type face 6, the first strut 2
Across the through-hole of turbine shroud 7；Through position 14 is also set up on pedestal 1, through position 14 passes through under shaft 13 and the second platform 11
End connection, the upper end of the second platform 11 is resisted against the side of the first platform 3；The abutting of second platform 11 and turbine shroud 7, second
After strut 9 passes through the second platform 11 and turbine shroud 7, one end of the second strut 9 wears the second compact type face 8 and lock nut
10, the other end of the second strut 11 is rotary with lower end lock nut 12；
It is reliable in order to position, it prevents nut loosening from bringing the variation of size, positioning is also set up between the first platform 3 and pedestal 1
Branch cylinder 15, the positioning branch cylinder 15 are set in the outside of the first strut 2.
It is cambered surface to prevent the abrasion of two platforms, the face that the first platform 3 is contacted with the second platform 11.
The diameter of first strut and the second strut needs the internal diameter with the through-hole on turbine shroud to match.
As a result of the positioning of locking nut form, therefore, position of the platform on strut is adjustable, has adapted to different rule
The turbine shroud of lattice；And the pivot structure of the second platform, it has been also adapted to the rotation angle of different housings.
